26 Claims.

This invention relates to typewriting machines. One of the objects of the invention is to provide a typewriter with novel operatingy mechanism between the keys and the types which permits the arrangement of keys to beentirely independent ofthe order in which the types are.A

positioned.

Another object of the invention is to provide a typewriting machine with a exible cable connection between each key and its associated type.

-Another object of the invention is to providev an improved key lever construction for a type- `writing machine in which the keys will have substantially straight-line movement with a minimum of resistance in the moving parts.

Another object of the invention is to provide al typewriter in which the position of the type assembly and paper holding mechanism may be entirely independent o! the arrangement and position of the keys. f

1 Still another object of the invention is to provide a typewriter with a force transmitting mechi anism between the keys and the types by means of which a minimum of force is required to cause a type tol print, providing a light touch.

Another object of the invention is to provide a I typewriter with a combination type shifting' and paper feeding arrangement by means of which a single key is used either lto advance the paper a predetermined amount through the machine or to shift the types.

A further object of the' invention is to provide` a typewriter having a plurality of types arranged to be printed simultaneouslyywhich includes a shift mechanism whereby a selected number of type bars are shifted for printing other types Vwhen the keys are operated together with the shift mechanism. l

Ari important object of the .invention is to provide a stenotype machine which is compact, being For la fuller understanding of the nature and objects of the invention reference should be had to the following detailed description taken in connection with the accompanying drawings, in which:

j'Fig. 1 is a plan view oi a typewriting machine embodying our invention;

. one of thepaper feed rollers;

but slightly larger than the keyboard, and which `is lighter in weight than those heretofore used.

lAnother object of. theinvention is to provide a paper feed mechanism which will start feeding the paper when a key is depressed but which will complete the feedingl operation `before the4 type bar strlkesthe paper.

Otherobjects of the invention'mill in' part be obvious and will in part appear hereinafter.

The invention accordingly comprises the features of construction', combinations of elements, and arrangement of parts, which will be exemplified in the constructionshereinafter set forth, and

the scope of the application of which will Abe indicated in the claims. i

Fig. 1 3 is a sectional front view of the roller of Fig. l2 taken on the line |3-I3 o f that. ligure: Fig. 14 is an enlarged fragmentary view of the connecting' means between. the keys and type bars; and v Fig. 15 .is a botto'm view of me end or the typej writer containing the types and platen.

Referring now more specifically to the draw-v ings, theinvention is shown in connection'with a typewriting machine in which a plurality 0f types are adapted to be printed simultaneously y across one line oi a paper strip, the strip being adapted to advance a predetermined distance through said machine at each operation of a type or 'a plurality of types. Such a machine may be one designed for use with stenotypy in which sounds are represented by various letters or comscribed.

as comprising a plurality of keys I5, I6, and I1; 5' i arranged in three rows, as indicated, keys I5 and I6being used to record consonantal sounds. while keys I1 are fewer in number and are used to record vowel sounds. -As will be seen vfrom Fig. 1,

the. casing I8 which houses the entire machine, 10 is but little larger than the keyboard itself and contains atthe leit side thereof the platen I6, over which the strip of paper is fed, the paper thu's feeding into the side of the machine in a direction transverse to the usual direction of Ieed- 15 ing paper into such machines. The types are y also housed at the left side of the machine' adjacent the platen in a manner to be described later. An inked ribbon 2| is caused to move between the platen and types to furnish the. ink for 20 printing The frame work of the machine comprises two end plates 26 and 21 (Figs. 1 to 6), the former at the left end of the machine and the latter at the right end ofthe machine. These plates are held in spaced relation by four rods (Figs. 2 and 4) The rod 30 at the lower front of the machine is secured to the plates 26 and 21 by means of screws 3i and 32, respectively, which pass through the plates. At the rear of the machine we pro.- so

vide three such rods: 33 in the lowermost posi-- tion, 34'about midway up, and 35 near the top of the machine. These rods are held in place by suitable screws which pass through the end plates,

similar to the screws 3I and 32 securing the 85 rod 30.

Plate 25 is provided with downwardly extending feet 36 and 31 at the front and rear corners i thereof, which may be anged over to form supy ports for rubber feet 36 and 39, respectively. In 0 a similar manner` the plate 21 is provided at its lowermost corners with front and rear feet 40 and 4I which-areilanged over to receive rubber feet 42 and 43, respectively.

The two rods 34 and 35 form the bearing rods .15

for the supporting mechanism for the keys I5, I6,

and I1, and the novel manner of supporting these keys is best illustrated in Figs. 6 and 10. Certain parts of the key supporting mechanism are substantially the same for all keys, and hence only 5o the one se't of these need be described. In Fig. 6 a pairof upper and lowerv lever arms 46 'and 41 are shown supported respectively on the rods 35 and 34. The lever arm 46 has a portion 46 at its rear end bent over so as to form two spaced bearing flanges 49, provided with aligned holes through which the rod 35 passes. These bearing iianges 49, therefore, permit the lever arm 46 to pivot about the rod .35, at the Sametime the spacing of the flanges maintaining the lever arm o against anysidewise movement. In the same manner, the lever arm 41 is provided with a bent over portion 50 at the rear, which provides two spaced anges 5I having aligned holelthrough which the rod 34 extends to permit the lever arm g5 41 to pivot about the rod 34 without any sidewise movement. It will be seen inil'igs. 6 and 10 that the portion 46 connecting the bearing anges 43 oi the lever arm 46 is' at the top, while the lever arm 41 has its connectins portion 50 at the bot- 70 tom. A pair of these lever` arms 46 and 41 are used not only to supporti'eech key, but two pairs are also used to support the combination paper feedingxandptypeshifting key to belater de- Awhere necessary, by washers 44 (Fig. 2), and the nel member 69 is secured in any desirable mana buiIer for the lever arms 41. These arms have Bomeof the lever arms 46 and" have 75 Vthe left, this being determined by the manner in which the lever arms it on the pivot rods for the desired spacing of the keys.

In Fig. 6, two of the keys I5 and I5 are shown. The key I5 is mountedon a member 55 which has a vertical portion 56 and an upper portion 51 extending at an angle rearwardly thereof, as indicated. The lowermost end of the-portion 56 is pivoted to the lower lever arm 41, as at 5B, by a suitable rivet or other means, and the upper most end of the portion 56 is pivoted tp the forward end of the upper lever arm 46, as at 59. When the key I5 is depressed, the member 55 moves downwardly in substantially straight-line A movement as the two lever arms 46 and 41 pivot about the rods 35 and 34, the lowermost position of the key I5 being shown in dot-and-dash lines in Fig. 6. A spring 60 is provided attached to the rearmost end of the portion 56 of each of the lever arms 41 with its other end attached to the rod 33 in anyrdesired manner, so as to cause the spring to be extended whenthe lever arm 41 is depressed, the 4spring'thein tending to raise the lever arm 41 and the associated members when the pressure is removed. The lever arms 46 are separated from each other along the rod 35,

lever arms 41 are similarly separated on the rod 34 where necessary by means of washers 45.

A Z bar 64 is provided extending completelyacross the machine from the plate 26 to the plate 21 and secured to the plates in any desired manner, as by having end-portions 65 (Fig. 3) iitted into slots in the plates. This; bar has a lower horizontal portion 65. extending forwardly from a vertical portion 61 and a second horizontal portion 66 at the top extending rearwardly of the vertical portion 61. The Z bar is positioned between the two lever arms 46 and 41 and just forward ofv the pivot rods 35 and 84. A channer to the under surface yof the horizontal portion 66 and carries a felt pad 10 which acts' as small flanges 1I bent over from the upper edge thereof to engage the telt pad 16. The return of the key to its uppermost position is thus cushioned and made substantially noiseless.

The z bar 64 and pivot rods 34 and 35 are rigidly supported with respect to each other at the center of the machine by means of a curved bracket 12 (Fig. 5) the ends of which fit over the rods 34 and 35 and the center section of which is secured to the Z bar by the screw 13. This bracket also acts as a spacer for the lever arms at the center.

The keys I5 are mounted on members 15 which l are identical with the members 55, although mounted vin reversed position so that' the upper portions extend towards the front ofthe machine. These members 15 are mounted on lever 4 arms which are identical to the arms 46 and y41. The keys I1 (Fig. 5) are mounted on members A16 each of which has a vertical portion 11 corwith the springs 60 so that all of the keys I between the two plates 95 and 96 on a suitablev are returned to their normal positions when the pressure is .removed therefrom. f

'.Wehaveprovided a novel method of trans-v mitting motion between the key lever assemblies l i and the types, land by means of this novel connection, we are able to place the type assembly in any position with respect to the keys, andv arrange the various types in any desired relation irrespective of the particular order of the keys. The motion is transmitted by means of iiexible cables $2, as indicated in Figs. 4, 10, and 14, encased in guide 'tubes 80. Each cable 82 comprises a closely wound coil of wire, the turns being so close together that the lcable itself is substantially non-compressible,l but becausesofv the formation itis extremely flexible. Each guide tube 80 is a seamless metal tube with its ends anchored in the machine. It may be bent in almost any desired shape but the 'cable will 20 still have free longitudinal movement therein, such longitudinal movement being enhanced and made more elcient by the smooth inner walls of the. tube.

A plurality 'of these guide tubes 80 are provided extending between the horizontal iiangel 68 of the Z bar 64 and the typeassembly. The tubesA 80 pass up through suitable holesin the horizontal flange 68 and have their ends belled over, as indicated at8I, so as to secure the tubesl 30 rigidly to the Z member 64. Each tube is secured to the Z member l immediately beneath` one of the arms.46, so that the upper ends of all of the tubes-80 are arranged in a row on the Z bar ilange, as indicated at right hand side of Fig. 2. One of the coiled exible cables 82 is provided inside of each tube, the cable being of such a diameter that it will slide through the tube longitudinally, regardless of the bends in the tube,. and the upper end of each of these cables is ado justably secured to the lever arm 46 which is immediately adjacent to it.A In order to securel the cable '82 to the lever arm 46, We provide a ange 85 (Figs. 4 and 14) on the forward end of the member 48, against which is vsecured a clamp`86 by means of. a screw 8l which passes through both the clamp and the flange 85. .The clamp may also have its inner side provided with a plurality of grooves 88'toy iit the turns in the cable so as to lock the cable flrmly Vin position with respect to the 'lever 4 6. By means of-this removable clamp the effective length of the cable may be adjusted. The manner'of vconnecting the other end of the cables so as to operate the type bars will be describedhereinafter. 4

The platen I9 `and type assembly are mounted at the left of the machine between a pair of plates 95 and 96 which extend to the left of the plate 26 and which have the configuration shown in Fig. 7. 'I'hese plates arev secured tothe plate '50" 26 by means of anges 91 and 90 (Figs. 2 and 3),

' the formervbeing held in position by the screws securing thevrods 33 and 34 to the plate 26, and the latter being held -by the screw 3| and an aclditional screw 99. The platen I9 is mounted 86 shaft |00 whichl is secured to the plates 95 andv` 96 in any desirable manner.

' In the particular ste'notype machine used to illustratefthe invention certain types arev nor 70 mally caused to print when the associatedkeys are depressed.` These types are arranged in a y single row. However, .additional types are vprovided to be operated when some of the same keys v type |06.

lever |09 is rst caused to rotate rapidly about -viewed in Figs. 8 and 9, and to thereupon slow of a shift mechanism. I'hese types are fewer in number and are mounted below the other types. We therefore use two different forms oi' type bars'. The type bar |05 (Fig. 9) carries the single type |06, while the type bar |01 (Fig. 8) carries, in addition to one of the types |06, another type |08 which is mounted immediately below the In order to support the type bars |05 and |01, we provide a plurality of levers I|09 which are pivotally mounted on a shaft ||0 which extends between plates and 96 and is rotatably mounted in these plates. These levers are 4substantially vertical in position and carry the type bars at their upperends. The type bars |05-are ixed to the levers |09 in any desirable manner, as by tightlyriveting them to the levers at III. The type bar |05 is mounted substantially horizontal and when the lever |09 carrying it rocks in a counter-clockwise direction, a-s. viewed in Fig. 9, the type |06 will move towards the platen I9 striking the ribbon 2| against, the paper 20 and causing the type to print thereon.v

The type bars |01 are mounted pivotally on the levers |09 by suitable rivets ||2 which will permit rotation of thetype bars with respect to the levers. Each type bar |01 has an extension ||3 toward the right thereof terminating in a circular end which fits into a channel 'member ||4 extending from front to back of the machine and mounted for vertical movement in a manner to be hereinafter described.- Rotation of the lever arm' |09 supporting the type bar |01 will cause that type bar, when in normal position, to move the type |06 towards the platen, to print the type on the paper, at the same time permitting the of the levers |20 is also mounted 'substantially vertically in the machine and carries a cam extension |22 which is adapted to engage a roller |23 rotatably rmounted on the adjacent lever |09 a little more than half way 'up the lever. The arrangement of the cam |22 and roller |23 is such that when the lever |20 is 'rotated in aclockwise direction, as-viewed in Figs. 8 and 9,'the

its pivot ||0 in a counter-clockwise direction, as

-down as the-point of thecamrounds the end of the roller arid to move slower and with greater force against the platen as the lever 20 is further rotated.

.The shafts I|0 and I2I are secured in the plate I 95 and 96 by means of a key -I I8 which is held against the plate 96 by a screw ||9, the ends of. the key ttinginto slots cut into the shafts adjacent the ends thereof.

' Thelevers |09 are spaced `from eachother in regular orderfrom-front to back of the machine and in order to maintain the proper spacing and to keep the levers in theirv respective planes, we provide a comb |24 (Figs. 9 and 15) for the lower ends of the levers and a comb |25 for the upper ends thereof (Fig. 9) The comb |24 is mounted at the bottom of the plates 95 and 96 andvcomprises a flat plate having end extensions |26 which t tightly into suitable slots provided for that purposevin the bottom edges of the plates, as indicated. The right side of the comb |24 is s provided with slots v|21, there being one slot for each of the levers |09 which rock in the slots and are thereby maintained in position.

The upper comb |25 comprises a flat plate paper strip 20 is caused to move in the machine which extends slightly beyond the platesh95 and l 96, being mounted upon flanges |28 which `extend outwardly from the lowest point of the cut-out portion |29 of the plates 95 and 96', the comb being held in position against the flanges by means of long screws |30 which also act as guides for the ribbon 2|. 'I he right side of the comb |25 is bent upwardly and is provided withslots |3| to receive the upper ends of the levers |69 between the rollers |23 and the type bars |05 and |01, thus permitting each lever |09 to swing about its pivot from side to side of the machine shaft and which are mounted on a frame |33la pivoted on an auxiliary shaft |44. The shaft |44- while kept in its individual plane. An angle plate |32 is weldedto the lower surface of the-comb and is provided with aplurality Aof holes along the lower edge for securing the upper ends of a plurality of springs |33, the lower'ends of which are attached to arms |34 formed integral with and extending to the left of the lower ends of the levers |69.

A tube .anchor bar |36 extendsacross the machine between the plates 95 and 96 and is attached to the feet 36 and 31 by means of suitable anges |31 which are bent over the edges of the plate 26 and are secured in place by means of suitable screws |38. The lower end of each of the tubes 80 issecured in this anchor bar |36, the tubes passing through suitable holesin the'bar and having their ends belled over to secure the tubes in place. Each of the tubes is secured in the tube anchor barv at a point invalignment with one of the levers |20 and the other end of each of the cables 82 extends out of the end of its guide tube Bil-and is secured to the edge of the alignedlever |20 by suitable clamping means |39.

By depressing one of the keys in the typewriting machine, the lever 4'6 to which that key is loperatively connected acts to depress the cable 62 connected to it and to force the cable through the tube 80, thus pushing the other end. of theV cable out of the other end of the tube and rotatlng the lever |20 in a clockwise direction, as viewed in Figs. 8 and 9. This causes the cam |22 to rotate over the roller |23, thus causing the lever` |09 to rotate in a counter-clockwise direction towards the platen and to press the type against the platen. The lever arms |09 are caused to move to their normal positions again by means of the springs |33 when pressure is removed from the keys. This pushes thelever |20 towards the right and lthe cables 82 Iback up through their guide tubes 09. The key levers are at the samel time returned to their normal positions by the springs 60, already described.

The use of the cables 82=and guide -tubesl89 provides connectidns between the keys and types W planeV towards the rear of the machine to reach its particularlocation in the Z -bar 64. .Inadditionthe tubes aredustproof and protect the cables .from the front of the machine. In order to accomplish the feeding of the paper, we provide a pair of rollers |35 l(Figs. 1, 1, and 10) mounted on spindle |43 whichare arranged parallel to the `is mounted on brackets |44 which are secured. one adjacent each of the plates 95 and 95 to a shaft |40 rotatably mounted in upstanding members |4| and ,|42 of the plates 95 and 96 respectively. 'I'lie shaft |44 is thus positioned above the shaft |43 so that whenthe shaft |40 is rotated in a counter-clockwisev direction as viewedfrom in front of the machine, the frame |43 will be moved towards the left.

The rollers |35 are provided with one-way ball clutches, as illustrated in Figs. 12 and 13. Each of the 'spindles |43 is provided with a. sleeve |45 .which .has ratchet-like teeth |46, as seen in Figs.

= Rotation 'of the roller in'a clockwise direction is freely permitted, because the balls tend toroll towards the large ends of the ratchet teeth, while rotation in a counter-clockwise direction vis prevented because the balls tend to wedge in bctween the sloping teeth of the ratchet and the outer shell |41 of the roller. When the rollers |35, therefore, move towards the leftthey do not roll'but push the paper-together with the platen lI9 towards the left, thus causing the platen to rotate and the paper to feed a predetermined distance through the machine. When the rollers move to the right they roll freely and the paper is not moved.

The movement of the rollers |35 is controlled by means of a rack |5| (Figs. 2, 8, and 10) which meshes with aH gear |52 rigidly attached to the shaft |40. The rack I5| is at the upper end of a bell crank lever |53 mounted on'a pin |54 secured to the plate 96 by a nut |55. The lower arm |56 of the bell crank lever extends to the right through a slot |51 (Figs. 3 and 8) provided to receive it in the plate 26. The arm |56 extends slightlybeyond the plate 26 and has attached to it the end of a cable |58, which passes through a tube |59 which has its forward end anchored in a small bracket |60 securedto the plate 26 by suitable screws |6|. The tube |59 extends upwardly and rearwardly, close to the plate 26, and therear end is anchored in a clamp |62 secured to the horizontal portion 66 of the Z bar 64 by means of ,a screw |63. The tube |59 and cable |56 are similar to tubes 60 and cables 82.

The rear end of the cable |58 is attached toa bail |66 which is mounted on two lever arms |66 pivotally supported on the rod 34, there being one llever arm adjacent the plate 26 at one end of the machine .and the other adjacent the plate 21 at the other end. The cable |50 is attached to the arm |66 adjacent the plate 26 by means of a clamp |61 and screw |63. The bail |65 comprises a channel shaped member with a. pad |69 of felt within it. the channel being mounted so that the padfaces the rear of the machine. Movement of about the rod 34.

aaiaoos I the bail towards vthe front, pivoting about the rod 34, willcause the cable |58 to 'be pushed through the tube |59, which rotates the bell crank lever |53 in a clockwise direction, as viewed from in front of the machine, so as to move the rack I| to the right under the pinion |52. This rotates the pinion in a counter-clockwise direction, thus `moving the rollers |35 towards the left and feeding the paper. The bell crank lever |53 is urged towards its normal position by means of a spring (Fig. 8) on the left side of the plate 26 which A cover plate isa is provided between the top of the plate 28 and the right hand edge of the has its lower end connected to thearm |56 of the mechanism is operated. To this end each of the i lower lever arms 41 is provided at its rear end with an upstanding arm |12 which is adapted to engage the felt pad |69 of the bail |05. Whenl any one of the keys is depressed the corresponding lower lever arm 41 is rotated in'a clockwise direction, as viewed in Figs. 3 to 6, inclusive, and

10, which causes the arm |12 on that 4particular leverarm to press againstv the felt pad |69 and thus causes the bailto swing forward, pivoting bail |65 is cushioned by means of a lpair of cups |13 (Fig. 4) positioned at spaced intervals along the Z bar 64 and containing felt pads |14. The

- plate 21 and the lowermost rod 33.

The above arrangementprovides for movement- The forward movement of the of the paper forward in the machine when any of thekeys is depressed. In order to prevent thepaper from moving back again when the `feeding rollers |35 return to their normal position, we provide another roller |15 which is -mounted on a bracket |16 which extends across the-machine between the plates 95' and 96. The bracket |16 has two downwardly depending arms |11 and |,18 at the backand front Arespectively which are rotatably mounted on the shaft |40. The central portion of the bracket is cut out forming side members |00 which extend towards theleft and then downwardly and are formed integral with a toothed member '|8I, against which the paper may be torn when it is desired. to remove a portion of the paper from the machine. At the center of the bracket |16 we provide a downwardly extending'ange |82, which supports the bearing |83y for the roller |15. The roller |15 is provided with a, one-way clutch mechanism similar to the rollers |35 already described.

The angel |11 is provided with a downwardly extending lug |84 (Fig. 9), to whichis connected one end of a spring |95, the other end of the spring being connected to a pin |86 attached to the plate 26. This spring urges the bracket towards its lowermost position with the roller |15 in contact with the paper which passes over the platen I9.

Two fine wire-springs |81 are attached tothe rearrnost portion of the bracket I16,and these springs extend towards the left as Aindicated in Figs. 7, 8, and 9, to bear against the bearing pins |43 of the rollers |35, so thatkas these rollers move bracket |16. This'plate is pivoted on a shaft |89 plate 26 and is just wide enough to catch the edge |9| 'of the bracket |16, as indicated in Figs. 8 and 9. 'I'he plate |88 is urged downwardly to the position shown in Figs. 8 and 9 by means o'f aspring |92- which is wound around the shaft If it is desired to raise the rollers |35 and |15 from the platen I9, the cover plate |88 may ilrst be raised by means of an oifset portion |93 provided in the center thereof, whereupon the bracket |16 may be raised, and subsequently the frame |43i may be raised as shown in Fig. '1.

The pin |43 at the forward end of the frame |43*l may be provided with a knob I 94 (Figs. 1 and 12) to Jfacilitate raising the rollers.

It has been stated that the type bars |01 can be rotated about their .pivots ||2 to shift to a different set of types by movement ofthe channel member I I4. 'j'lhey channel member I I4 is mounted on a vertically extending plate 200 (Figs. 3 and 8) which is provided at its upper' end with a pair of upstanding guide fingers 20| which are guided in a block 202 secured-to the plate26 by means of a screw 203. The block 202 is provided with grooves on opposite side edges to t the fingers 20|, and acts to space the-plate 200 a short distance from the member 26 although permitting vertical reciprocation thereof. In a similar manner, the lower end of the plate 200 is mounted for vertical reciprocation in a block 204 which is supported at the lower end of the plate 26 by means of a screw 205. The block 204 is similar to the block 202l and is provided with grooves on the side edges thereof which receivel downwardly extending l fingers 206 of the plate.. The plate '200 is thus mounted vfor vertical reciprocation through a. limited distance. The channel member ||4 is se' cured to the plate 200 by means of an upwardly extending member 201 which is welded or otherwise rigidly secured to the channel |4 and is held in place against the plate 200 by a screw 208.

The plate 200 carries a roller 209 which extends out towards the right of themachine and lies in a cam slot 2I0 formed in an irregularly shaped plate 2I| which is pivotally mounted on the left side of the plate 26 by means of a screw 2 I2 which is shown exaggerated in length in Fig. 10. Onv

the right side of the plate 26 and pivotally mounted on the plate by the same screw 2|2 is a segment of an internal gear 2I3, this gear being secured to the plate 2| I by means of a pin 2 I4 (also shown exaggerated in length in Fig. l0), so that 'the two always move together. The gear 2|3 is provided with an arc of `internal teeth 2I5. Y The pin'2I4 passes through a suitable openingv 2|6 in the plate 26 so as to permit the plate 2|I and the gear segment 2|3 to rotate through a limited angle'.

A shaft 2|1 is rotatably mounted between the plates 26 and 21 at a point just in front of the lower lever arms 41, the shaft extending through the opening in the internal gear member 2|3. The left end of the shaft adjacent the internal gear member is provided with a pinion 220, preferably made of fibre and having teeth at each end, the teeth at the left end being arranged to mesh with the teeth Il in the gear member 2I3,

' so that when the snm 211 is rotated in the proper direction, the gear member 2 I 3 is rotated about `its pivot 212 to rotate the plate 2I| causing theV slot 2|0 in the plate 2||l to raise the roller 203l and the plate 200 which is attached to it.

In order to rotate the shaft 2|1, we provide a bar key 2,25 which is mounted to the rear of the keys I5 and can be depressed simultaneously with, any one of those keys inthe rear row. This bar key-is mounted on' two members 228 and 221, the former at the left side of the machine, shown in Figs. 4 and l0,l and the latter at the right side of -the machine, shown in Fig. 5. These members are alike and each has a horizontal portion 228 extending forwardly and another vertical portion229 integral with the forward end of the horizontal portion 223. The forward edge of the vertical portion 223 is provided with rack teeth 230 arranged in an arc so as to mesh with the teeth 23| on the right end of the pinion 220, in the case of the member'223, and to mesh .with a pinion 232 iixed on the other end of the shaft 2|1, in the case of the member 221. The members 225 and 221 are'each mounted upon'two of the levers 43 and 41, the upper end of the verti'- cal portion 223 being pivoted tothe forward end of the lever 43 at 232 while the lower end of the portion 223 is pivoted to the forward end of the lever 41 at 233. The levers 43 and 41 supporting the members 225 and 221 are pivoted on the rods 35 and 34 respectively, as already described in connection with the key supports, and therefore when the key 225 is depressed, the portion 223 containing the rack teeth 230 moves downwardly and the arcof the rack -teeth is so designed that it will maintain the teeth in contact with the teeth on the pinions 2'20 and 232, irrespective of the slight rocking movement of the members 226 and 221 caused by the lever arms 43 and 41 moving about their pivot points. Therefore, when the bar key 225 is depressed, the shaft 2|1 is rotated Aand the channel ||4 is lowered, thus rotating the type bars |01 and causing the lower type |03/ on any oneof them to print when the associated key is depressed. The springs 50 attached to the Arear ends of the particular levers 41 return the bar key v225 toits normal position after the 'pres' sure of the nnger has been removed from it.

It will be noted that since the lever arms 41 have the upwardly extending arms |12 at the rear thereof, the bail |65 which operates the paper feed mechanism will also be moved when the ber key 22s is depressed. Thus the ber key M 225 is used to advance the paper strip when operated alone. Whenso operated, the rotation of type bars |03 will have no effect, since these type bars are not moved towards the platen. v.It

is only when the bar key'225 is depressed' simul-v taneously with one of the keys |5 that the lower types |00 on the type bars |01 are printed.

The, ribbon 2| is arrangedto move between the platen and the types any time one of the .keys is depressed. so that duringoperation of themathe ribbon each time the types strike. In the machine iilustrated, we use a continuous ribbon which passes completely around the machine and is driven by a roller 235 (Figs. 1 and 11) which. is rotatably mounted at the forward corner of the machine on e vertical shaft supported betweenA the foot '40 bn the forward edge of the plate 21 95 over it.l chine, the ribbonv is intermittently Emoved with respect to the type to present a different place` on plate 21 is cut out at 231 in order to receive'the roller. The roller is provided with a bevel ge'ar 238 at its upper end which meshes with another bevel gear 233 on a'clutch member 240 rotatably s nountedbetween a portion of the bracket 236 nd another bracket 24| which is also secured to the plate 21. The clutch member 243 is a oneway clutch, similar in construction to the clutches on the paper feed rollers |35, and is driven by an l0 arm 242 which extends downwardly from the left end thereof. A link 243 is pivotally connected to the lower end of thearm 242 and its other end is pivoted to one arm ofl a bell crank lever 244 which is pivotally mounted on the plate 21 by i6 meansof a pin 245 on the left of the plate. The

pin 245 is long enough to space the bell vcrank lever 244 so as to align with the link 243. The other arm 246 of the bell crank lever 244 is pivotally connectedto the forward end of a link 241 which extends towards `the rear of the machine where its other end is pivoted to a lug 245 atj tached to the paper feed bail |65. v

The arrangement is such that every time the bail |65 moves towards the front of the machine 1 25 when any one of the keys is operated, the link L 241 is pushed forward thus pushing the lever 243 and causing the clutch arm 242 to rotate through a limited angle in a clockwise direction, as viewed in Fig. 6. This causes the bevel gear 239 to rotate by virtue of the one-'way clutch, which in turn rotates the roller 235 whichv advances the ribbon. Upon the return of the paper feed bail to its normal. position, the link 241 is withdrawn towards the rear and the link 243 pulls 35 the clutch arm 242 rearwardly. However, by virtue of the clutch operation, the gear 233 does 'not turn during this return movement, and therefore the roller 235 does not turn and the ribbon is stationary.

40 lIt will be noted from an inspection of Fig. 6,

that the bell crank lever 244 only has to rotate a short distance before the link 243 has reached its forward 'limit of movement and further slight rotation of the bell crank 244 does not move the link zu. .By means of this toggle the ribben is caused to stop moving before the full stroke of the key has been reached and before the types strike against the platen. Therefore, the ribbon is stationary when the type strikes and therey is m no tendency to' tear the ribbon at this time.

'G0 through holes 255 in the upper plate 256 of the I roller. The felt `pad absorbs the ink and inks the ribbon as the ribbon passes over it. 'I'he roller 25| merely has afelt" periphery which absorbs any eXCeSS ink'-fr om the ribbon as it passes At th'e'left end of the-machine, we provide a Vribbon guide 251 mounted on the corner of the A plate 26 which guides the'ribbon over the corner of, the plata* From the guide 251 the ribbon 10 passes over the pins |30, these being soarranged 1lslightly'beyond the plates 20 and 21 and is proa'seaeos vided at the extreme ends with curved portions 259 and 260 to guide the ribbon over the edges of the. plates 26 and 21. From the curved portion 260 of this plate, the ribbon moves across the right end of the machine to the driving roller 235.

The casing 23 is preferably made in two parts which clamp together at the right side of the machine' by means of the clamp 263 andis secured to anges 26|., 255, 265, and 251, formed on the feet, by means of screws 268, 269, 210, and 21 i, respectively. A plate 212 (Figs. 3 to 6, 8, and 9) is preferably mounted on the bottom of the machine and is held against the plates 26 andv guide for the paper strip .which then may be fed into the right side of the machine from a stack .of paper kept at that side, the left end of the plate delivering the paper to the platen, asindicated in Fig. 9. A curved plate 215 is mounted beneath the platen i 9 'for' guiding the paper strip onto the right side of the platen. This plate has to said member, clamping means on said'member AWe claim: i

From the above description it will be apparent that we have provided a typewriting machine in which the novel arrangement of transmitting force from the keys to the types by means of the flexible cables permits the types to be positioned anywhere with respect to the keys and in an order entirely independent of the order of the keys, since the tubes containing the flexible cables may be bent and turned-in any direction. This is an important feature of the invention because it permits the working out of a keyboard which is the most efficient for speed and ease of manipulation of the ngers without interfering with the necessary order/of the types for printing across the paper. At the same time. the arrangement permits the types to be placed in any way with respect to the keys, thus allowing the whole machine to be made in a compact form asv 4will be evident from the various figures which lindicate that the machine illustrated is but little larger than the keyboard itself. Attention is also drawn to the arrangementI of the key lever assemblies which eliminate the use of a comb to guide the keys and yet support the keys against substantial sidewise movementand at the same time give them a substantial straight-line movement which is an aid to faster and smoother manipulation thereof. Transmission cf force between the key and the type Vbar is such as to increase the 'force of the type against the platen towards the` end of the downward stroke of theV key, and the whole assembly provides a substantially silent operation with a feather touch, re-

Aquiring very little effort on the'part ofv the operator to depress the keys.
